A messaging service node sends encoded messages to wireless devices prompting the devices to capture media (e.g., audio and/or image) and send the media file to a network address specified in the message. The service node may be managed by a wireless service provider, and provides this media capture message service for unrelated, independent entities such as insurance companies, health or medial companies, government agencies, etc. The encoded message may take the form of a Multimedia Messaging Service (MMS) message, but other formats are possible. The media is preferably captured by a camera or microphone incorporated into the wireless device.
